1. The problem statement, all variables and given/known data For each expression of displacement (x) below, write down the mathematical functions for velocity (v), acceleration (a), and pressure (Pa). Assume a maximum amplitude (A) of displacement = 1. Units are not required. Hint: Think about the phase relationships of pendular motion. You can express your answers by using a different trigonometric function or by simply changing the phase of the given function. If the instantaneous displacement of particle x can be described by the function x = sin(ωt + θ), then write down the mathematical functions for v, a, and Pa. v = a = Pa = 3. The attempt at a solution I really don't have much of an idea of where to begin. I think it has something to do with a time domain waveform, but a nudge in the right direction would really help!
